While I dont have a quick answer for you I may have the one the helps best.
Measure the thickness of all but the main leaf and build a block or spacer that you can put under the spring pack to mimick the height of the pack.
Disassemble the spring pack and bolt up the block you just made, cycle the suspension upward untill bumps are hit, measure collapsed length of shocks and note height and postion on frame. Then position the hoops there. Now you have full use of your shocks.
